DRAFT-EQUALIZER.

SPECIFICATION forming part of Letters Patent No. 318,374, dated March 3, 1885.

Application filed November 20, 1884. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE 0. Born, of Big Springs, in the county of Douglas and State of Kansas, have invented certain new and useful Improvementsin Draft-Equalizers; and I do hereby declare that the following is a full, clear, and exact description of the in-' vention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which Figure l is a plan View of nay-improved draft-equalizer for harvesters, and Fig. 2 is a side view of a portion of the tongue.

Likeletters indicate like parts in the figures.

My invention relates to draft-equalizers for mowers, harvesters, and similar agricultural machines in which it is desired to overcome side draft; and it consistsin the improved construction and combination of parts of the same, as hereinafter more fully described and claimed.

In the accompanying drawings the letter A indicates the frame of a harvester, to the side of which is secured the forward]y-projecting tongue B, the inner end of which is braced by means of an oblique brace, C, hinged or other-.

wise movably connected to the frame of the harvester,projecting obliquely from the tongue to the side at which the lateral draft is. A clip or stirrup, D, is secured upon the under side of the tongue, and has a laterally-pro jecting perforated bar, E, which corresponds to a similarly and correspondingly perforated laterally-projecting bar, F, which is secured upon the under side ofthe tongue, and asheave,

G, is journaled upon a bolt, H, which is secured in one pair of perforations in the two flatbars. Another sheave, I, is journaled upon a bolt in the rear endof the clip D, and a rope or chain, J, passes over opposite sides of the two sheaves, having at its forward end the doubletrce K, secured to the ends of which double-tree either single-trees or double-trees may again be secured. The rear end of the rope or chain is provided with a clip, L, having perforated ends, through which a removable bolt, M, passes, which bolt passes through one of the perforations N in a fiat bar, 0, which is secured transversely in the rear portion of the harvester-frame. By means of this removable bolt the clip may be changed from one perforation to another, closer to or farther from the point at which the strain and lateral draft is in the machine, and the forward pulley or sheave upon the shaft may likewise be changed from one pair of perforations to another in the laterally'projecting bars, rendering the draft and strain upon the tongue and in the machine adjustable, according to the number of draft animals used and to the amount of resistance from the grain to be cut.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States- The combination, with the frame and tongue of a harvesting-machine, of the oblique-brace secured to the tongue and to the frame, the laterally-proj ecti n g perforated bars,the sheave journaled adjustably between the said bars, the sheave journaled upon the tongue to the rear of the former-sheave, the perforated transverse bar at the rear portion of the machineframe, and the rope or chain having the double-tree at one end and the clip and bolt at the other end and passing over opposite sides of the pulleys, as and for the purpose shown and set forth.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.
